SPECIFICATION forming part of Letters Patent No. 263,534, dated August29, 1882.

Application filed July 31, 1882.

To all whom it may concern Be it known that I, CHARLES A. KINNEY, ofMeriden, in the county of New Haven and State of Connecticut, haveinvented a new 1mprovement in Lamp-Burners; and I do hereby declare thefollowing, when taken in connection with accompanying drawings and theletters of reference marked thereon, to be a full, clear, and exactdescription of the same, and which said drawings constitute part of thisspecification, and represent, in-

Figure 1, a vertical central section; Fig. 2, a transverse section abovethe chimney-rest and wick-tube.

This invention relates to an improvement in that class of lamp-burnersfor kerosene-lamps in which the chimney-rest and deflector are arrangedto slide vertically to and from the base, so as to expose the wick belowthe deflector, as for lighting, trimming, filling, &c.

In the usual construction of this class of burners two rods have beenattached to the deflector and extended down through the base of theburner to the extent at which the deflector was intended to rise, thelower end of the rods headed, so as to be arrested when they strike theunder side of the base, and thus prevent the entire separation of thedeflector from the burner. This construction presents severaldifficulties: First, the projection of the rods through the baseincreases the height of the burner to that extent. Hence in packingjustthat much more room is required-a large item in the transportation ofburners. Again, it is desirable to employ upon a lamp-as large a burneras possible, frequently much larger than the collar of the lamp, and inso doing what is called a reducer is formed. Such reducer is shown inFig. 1.

A represents the screw part of the lampbase, and B its bottom. C is thereducer. Its upper end is internally threaded corresponding to thethread on the base. Below this screw portion it is offset, and itsdiameter reduced and threaded upon its outside, as at a, correspondingtothe neck ot'the lamp. Hence with this reducer applied this large burnerwill lit the small neck; or with the reducer removed the same burnerwill fit a large 'neck. Hence the burner is adapted to various sizes oflamps, it only being necessary that a corre- (No model.)

to work freely up and down thereon, the tubes serving as guides for therods, and forming stops at their upper end to prevent the entire removalof the cone, as more fully hereinafter described.

D represents the chimney-rest, and E the cone, arranged upon the base inthe usual manner. The base, chimney rest, and cone may be of any of theknown constructions, the chimney-rest and cone, however, being separateand detached from the base. Within the base are two vertical fixedtubes, (1, and from the cone two rods, 6, extend downward into saidtubes, and so as to move freely up and down therein. These tubes androds serve to locate the chimney-rest and cone in proper relativeposition to the wick-tube and base below, and permit it to be raised, asindicated in broken lines, so as to expose the wick for lighting orother purposes, and then drop down to place in the burner. The tubesextend up from the base to a height at least as great as the heightdesired for the cone, and so that when the cone is down upon the basethe lower ends of the rods will not pass through the base. To avoid theaccidental separation of the cone and chimney-rest from the burner, Imake the tubes of larger diameter than the rods 6, and form a head,f, onthe ends of the rods, which should practically fill the tubes, or so asto form a bearing therein. The upper end of the tubes is turned inwardclose against the rods, and so as to form an internal flange, it,against which the heads f will strike when the cone is lifted, as seenin broken lines.

By this construction the burner is of no greater length than it would hewere it not extensible. Hencetheheretoforeincreasedlength for suchextension is avoided and the burner is adapted to a reducer. Again, thewire rods are not liable to be bent, as they are when they I part andcorresponding rods attached to the extend down through the base of theburner, and which bending interferes with their Workmg.

Instead of making the tubes fixed in the base and the rods in the cone,this may be reversed, the rods fixed in the base and the tubes in thecone, so that the tubes in that case would slide upon the rods; but Iprefer to make the tubes fixed to the base and the rods to the cone, asbefore described.

I claim 1. The herein-described improvement in that class oflamp-burners in which the chimneyrest and cone are removable from thebase, consisting in the tubes (I, attached to the one other part Workingin said tubes, substantially as described.

2. Theherein-describedimprovementinthat 20 other part working" in saidtubes, the ends of 25 the said rods headed within the tubes and the endof the tubes turned inward to form a-stop,

substantially as described.
